Eyelash extension professional salon: Firstly use Lash shampoo and then Pre-treatment / Primer before eyelash extensions. it accelerates the initial adhesion and leads to longer retention of eyelash extensions.
Personal home care: Even if you wash your face, you may not be able to thoroughly wipe away between the lashes, so the lashes are often not managed hygienically. If you wipe your eyelashes with Lash shampoo, you can keep your eyelashes far cleaner.
